NTune continually crashing my system, now what?

Hello everyone,

I recently installed NTune and figured I would try the fine tune, as I’d never really pushed my computer and I was going to bed anyway. I awoke to both of my monitors with random color streaks across them. Now every time I turn on the computer everything boots up fine until I get to Windows. It is fine until I put in my password and everything loads up, and then it just crashes the same way as before. I’ve tried getting to NTune before it crashes and have also tried just not touching it but it’s all the same crash.

Here is what I’m running.

MSI P4N SLI
Geforce 7800 gt
2gb of ram
